Description	The role of facultatively apomictic members of the genus Pilosella was studied on different scales by a complex approach which included direct studies of population composition in field, studies of progeny of selected plants, which originated in the field, and artificial hybridizations. We used morphometric approach, studies of reproductive systems by both emasculation and analysis of progeny origins, isozymes to identify minimum number of genotypes, chloroplast DNA to identify haplotypes. The main results can be summarized into these points: 1. Analysis of population composition in two mountain ranges (the Krkonoše Mts., and Šumava Mts.) showed that facultative apomicts served as a mother plants for half of hybrids and hybridogenous species. 2. Progeny analysis of both, apomictic and sexual mothers showed that apomictic plants produce more variation with respect to ploidy level. 3. This was suppported by reciprocal experimental crosses between apomictic and sexual parents.
